A study on HPV mRNA test and colposcopy in HIV positive women for early detection of cervical intraepithelial lesions

Background: Sexually transmitted infections (STIs) have a profound impact on sexual and reproductive health worldwide. At any point of time, globally more than 290 million women suffer from HPV infection, one of the most common STIs. There are only few studies from India reported regarding the prevalence of HPV and cervical abnormalities among HIV-positive women. This study was carried out to estimate the prevalence of HPV and other genital tract infection in HIV positive women and correlate HPV mRNA test and colposcopic findings with cyto-histopathology in HIV positive women who are not on antiretroviral therapy (ART). Secondary objective was to benefit HIV positive women by making them aware about the importance of screening, early detection and treatment of various lower genital tract infections, CIN and cancer cervix.Methods: cross sectional observational study was conducted in department of Obstetrics and Gynecology, NSCB medical college Jabalpur (M.P.) from March 2015 to August 2016 on 70 HIV positive women in whom anti-retroviral therapy was not started. This study was approved by institutional ethical committee. The data was recorded in predesign coded case report form and statistical analysis was performed using the STATA 12.1.Results: In the present study, prevalence of lower genital tract infections in HIV positive women not on ART was 30.0% and the prevalence of high risk HPV was 5.9%.Conclusions: The study concludes that diagnostic efficacy of HPV mRNA test has similar diagnostic value as that of histopathology report

The Dictators’ Digital Dilemma: When Do States Disconnect Their Digital Networks?

When do governments decide to interfere with the Internet, and why? While many observers celebrate the creative use of digital media by activists and civil society leaders, there are a significant number of incidents involving government-led Internet shutdowns. Governments have offered a range of reasons for interfering with digital networks, employed many tactics, and experienced both costs and benefits in doing so.http://deepblue.lib.umich.edu/bitstream/2027.42/117569/1/2011_Howard-Agarwal-Hussain_Brookings.pd

Extraskeletal myxoid chondrosarcoma of thigh: a rare case report

Extraskeletal myxoid chondrosarcoma (EMC) are a rare entity of soft tissue tumors that occur predominantly in soft tissue of lower extremities. Here we present a case of 45-year-old female presented with left thigh swelling. MRI finding suggested primary neoplastic lesion. Fine needle aspiration cytology (FNAC) suggested myxoid soft tissue neoplasm/sarcoma. Morphological examination revealed typical extraskeletal myxoid chondrosarcoma with strong immunoreactivity for vimentin and focal immunoreactivity for epithelial membrane antigen (EMA)

Bacteriological profile and antibiogram of uropathogens isolated from obstetrics and gynaecology patients in a tertiary care hospital

Background: Urinary tract infection (UTI) is a common complication occurring in obstetric patients, posing adverse risks to both the mother and fetus. The aim of this study is to analyse the bacteriological profile and antimicrobial susceptibility pattern of uropathogens in obstetrics and gynaecology ward for the effective treatment. Methods: A total of 404 urine samples from pregnant women with different gestational age were processed for the isolation of uropathogens and tested against ten classes of antibiotics. Uropathogens from significant bacteriuria cases were isolated and identified by standard procedures from January 2020 to December 2021. Antibiotic susceptibility was studied by Kirby Bauer disk diffusion method. Results: Significant bacteriuria in 16.3% samples, Escherichia coli (E. coli) was the most common uropathogens followed by Enterococcus sp. and Klebsiella pneumoniae (K. pneumoniae). E. coli showed highest resistance to ceftazidime, cotrimoxazole and ciprofloxacin while exhibiting high sensitivity to imipenem, meropenem, and amikacin. Moreover, major proportion of isolates of K. pneumoniae were resistant against ceftazidime, ciprofloxacin, and nitrofurantoin; and for Enterococcus species against penicillin and gentamycin, but 100% sensitive to vancomycin and teicoplanin, and 92.3% to linezolid. Conclusions: There is a need for screening of antenatal patients for UTI and it is recommended that pregnant women should undergo periodic screening for UTI, so as to monitor the sensitivity pattern of the uropathogens and for the development of specific antibiotic policies based on local susceptibility patterns.

A Nuclear Localization Signal and a Membrane Association Domain Contribute to the Cellular Localization of the Tobacco Mosaic Virus 126-kDa Replicase Protein

AbstractA transient expression system using onion epidermal cells was used to investigate domains of the Tobacco mosaic virus (TMV) 126-kDa replicase protein involved in cellular localization. Initially, a nuclear localization signal (NLS), identified within the amino-terminus of the 126-kDa protein, was investigated for its functionality using fusion constructs containing the green fluorescent protein (GFP). Fusion of the amino-terminal 70 amino acids of the 126-kDa protein, containing the NLS, to a β-glucuronidase-GFP open reading frame (ORF), directed the accumulation of fluorescence to the nucleus. In contrast, similar constructs lacking the NLS or containing a mutated NLS sequence failed to accumulate within the nucleus. Additional investigations using GFP fusion constructs containing the first 178 or 388 amino acids of the 126-kDa protein also displayed nuclear localization. However, fusion constructs encoding the first 781 amino acids or the entire 126-kDa ORF did not accumulate within the nucleus but instead associated with the endoplasmic reticulum (ER), forming spot-like inclusions. Thus, a dominant ER association domain exists between amino acids 388 and 781 of the 126-kDa protein. Interestingly, a full-length 126-kDa GFP fusion construct encoding a nonfunctional NLS mutation also localized to the ER but did not form inclusions. Furthermore, a TMV mutant containing the same nonfunctional NLS mutation failed to replicate in protoplasts. Together these findings suggest that both the NLS and the ER retention domain contribute to the functional localization of the 126-kDa protein

Calcifying fibrous tumour: a rare case report of an exceptional lesion localized in retroperitoneum, mesentery and pelvis

Calcifying fibrous tumours are rare benign lesions affecting mostly children and young adults. A 17-year-old female presented with abdominal pain and abdominal distention. Physical examination revealed intra-abdominal mass occupying retro peritoneum and right iliac fossa. Excisional biopsy from peritoneum and mesentery were performed. Histopathologically, it was composed of hypocellular hyalinised collagenized stroma, spindle cells, psammomatous and dystrophic calcification and mononuclear inflammatory cell infiltration. Authors are here in reporting a case of calcifying fibrous tumour and discussing its clinical and morphological features with regard to the literature

Biliary atresia with hyaline cartilage at the porta hepatis: a novel finding of undetermined significance: a case report

Biliary atresia is an important cause of liver disease and morbidity in infants with unknown etiology. To date, only five cases of biliary atresia with hyaline cartilage at the porta hepatis have been described. We present the case of a 65-day-old male child, with further insight and detailed discussion of this heterotopia of undetermined significance.Keywords: biliary atresia, hyaline cartilage, liver diseas
